摘要
传统的模拟滤波器的设计过程复杂，计算工作量大，滤波特性调整困难，影响了它的应用。该文介绍了一种利用MATLAB信号处理工具箱（Signal Processing Toolbox）快速有效的设计由软件组成的常规数字滤波器的设计方法。利用MATLAB设计滤波器：可以随时对比设计要求和滤波器特性调整参数，直观简便，极大的减轻了工作量，有利于滤波器设计的最优化。
The traditional analogue filter design process is complex, the computation work load is big, the filter characteristic adjustment difficulty, has affected its application. The article introduced one kind using the MATLAB signal processing toolbox （Signal Processing Toolbox） the fast effective design the conventional analogue filter design method which is composed by the software. Using the MATLAB design filter, may contrast the design request and the filter characteristic adjustment parameter as necessary, direct-viewing simple, enormous reduced the work load, is advantageous optimization which designs in the filter.
